Hi:
Given the extraordinary number of hours of joy this game continues to give me (between playing the game, chatting about the game, making maps for the game, etc.), I think the price was extremely well justified. Paying $8.50 to see a 2.5 hour movie is exorbitant in comparison.
I also think that the changes to the game in Dom 3 make it well worth while paying for the newer version. But, obviously, this game trips my trigger. Someone with lukewarm interest would probably feel differently.
